Excursion to the Kola superdeep well

Tens of thousands of wells have been drilled in the earth’s crust over the past decades of the last century. And this is not surprising, because the search and extraction of minerals in our time is inevitably associated with deep drilling. But among all these wells, there is one and only one on the planet – the legendary Kola Superdeep (SG), the depth of which still remains unsurpassed – more than twelve kilometers. In addition, SG is one of the few that was drilled not for exploration or mining, but for purely scientific purposes: to study the oldest rocks of our planet and learn the secrets of the processes going on in them. It is located 170 km from Murmansk, not far from the village of Zapolyarny.
